In recent years,antiviral therapy for chronic hepatitis B infected patients has achieved great development along with the invention of nucleos (t) ide,nucleos (t) ide analogues,interferon α and pegylated interferon α.The development of antiviral medicine also proposes new demands for the clinical diagnosis and therefore promotes the development of laboratory diagnostic techniques in the detection of chronic hepatitis B.In this review,we focused on the clinical application in the quantitive detection of HBV DNA,and its significance on clinical evaluation,treatment options,follow-up and prognosis in antiviral therapy.

Purpose:To study the therapeutic effect of rhG-CSF upon the severe hypogranulocytosis of children with acute leukemia after intensive chemotherapy. Methods:After intensive chemotherapy, the comparison between the group with rhG-CSF treatment ( n =136) and the control group ( n =65) was made on the ANC dropping time, the incidence rate and the degree of severity of the infection.Results:The period of ANC ≥0.5?109/L was shorter in the group with rhG-CSF treatment than that in the control group ( P

Objective To isolate, culture and identify human neural stem cells from 7-week to 13-week embryonic brains and to study different suitable culture conditions.Methods By using serum-free cell culture and single cell clone test,the neural stem cells were isolated and cultured from 7-week human embryonic forebrains and 13-week human embryonic cerebral cortex in different conditions and immunofluorescence tests were used to identify the cells. Results The human neural stem cells having the abilities of self-renewal and multipotency were successfully isolated and cultured from different embryonic brains. In 7-week brain, the cells could form clones in different ways except in high concentration suspension culture.In 13-week brain, the cells could form clones only in middle concentration suspension culture and high concentration adhere-wall culture. In coated petri dish, the cells couldn't form clones.Conclusions There are neural stem cells in human embryonic brains. With gestational age increasing, the neural stem cells become more and more difficult to be isolated. High concentration adhere-wall culture can be used in embryonic brains with different gestation age.

Pemphigus is a severe chronic autoimmune mucocutaneous bullous disease. Glucocorticoids are considered as the first line of treatment for this disease. Dysfunctional uterine bleeding is also observed as a result of hypothalamic-pituitary-ovary axis dysfunction. This study reported one female patient with pemphigus vulgaris complicated with dysfunctional uterine bleeding upon systemic glucocorticoid usage. Before this disease was diagnosed, the patient experienced normal menstruation. The mechanism of dysfunctional uterine bleeding triggered by glucocorticoids is elucidated on the basis of case studies and literature review.

Objective To investigate the significance of sonographic patterns of thyroid calcification in diagnosis of thyroid nodule.Methods 235 patients with 355 thyroid nodules were retrospectively analyzed.Nodule calcification size,distribution and pattern were observed.Results The incidence of calcification in benign and malignant nodules was 30.3％ (89/294)and 73.7％ (45/61) respectively.The difference had statistical significance(x2 =24.3,P ＜0.01).The rate of microcalcification in cancer was 47.5％ (29/61),higher than that in benign one 3.1％ (9/294)(x2 =99.1,P ＜ 0.01).Coarse calcification in benign nodules and malignant lesion was 27.2％ (80/294)and 26.2％ (16/61)respectively.The difference had no statistical significance(x2 =0.42,P ＞0.05).Conclusions Microcalcification of thyroid nodules is a specific index for thyroid carcinoma.Any type of sonographically detected calcification represents risk of malignancy.Not only microcalcification,these cases should raise the suspicion of malignancy in coarse calcification,especially involving a solitary nodule and irregular shape.

Objective To investigate the effects of a variety of different methods of analgesia on postoperative pain and cognitive function in elderly esophageal cancer patients.Methods Sixty elderly pa-tients scheduled for the left into the thoracic esophageal cancer surgery were randomly divided into two groups (n =30).Group A:Before the closure of thoracic cavity to block intercostal nerve with 0.375% rop-ivacaine,followed by intravenous pumps for analgesia,formulation of sufentanil 3 μg/kg+flurbiprofen 100 mg,pump speed 2 ml/h,self-controlled analgesia 0.5 ml/pressing,locking time 15 min.Group B:Before the closure of thoracic cavity given sufentanil 10 μg+flurbiprofen 50 mg as loading dose followed by epidural analgesia pump,recipe with group A.Two groups were observed mini mental state examination (MMSE) score 1 d before surgery and 3,5,7 d after surgery,each time point visual analogue pain score (resting and exercise VAS)score postoperative within 48 h,BCS comfort score and effective pressing times of postopera-tive analgesia pump.Results Compared with group B,the rest and exercise VAS scores of group A at post-operative recovery,4,8,12,24,48 h were significantly lower (P <0.05);the BCS scores of group A at postoperative 4,8,12,24,48 h were significantly higher (P <0.05);the pressing times of group A at postoperative 4,8,12,24,48 h were significantly reduced (P <0.05);the MMSE scores of group A at postoperative 3,5,7 d were significantly higher (P <0.05);the incidence of POCD of group A on postop-erative 3,5,7 d were significantly lower.Conclusion Thoracic surgery perioperative multimodal analgesia (intercostal nerve block and intravenous analgesia)can relieve postoperative pain,reduce the incidence of POCD,improve the postoperative patient comfort and help postoperative patients with rapid recovery.

Objective To explore the initial therapy indications of acute immune thrombocytopenia (ITP) in children based on the classification treatment.Methods Three hundred and eighty newly diagnosed ITP cases were enrolled in this study from Jan.1st 2012 to Apr.30th 2013 in Children's Hospital Affiliated to Shanghai Jiaotong University.In total 380 patients,there were 214 male cases (56.31％) and 166 female cases (43.68％).The cases were divided into observation group and therapy group according to the initial platelet count which was ≤ 30 × 109/L or the bleeding over moderate volume or with active bleeding.Platelet values were observed in the observation group weekly,adrenal cortical hormone and immunoglobulin treatment were adopted in the therapy group,cases were followed up to Aug.30th 2013,9 months on the average.Results Three hundred and five cases showed overall response (80.26％) and 75 cases showed no response(19.74％).One hundred and seventy-eight cases were divided into observation group (46.84％),in which 133 cases (74.72％) showed complete response or response.Two hundred and two cases were included in therapy group (53.16％),in which 167 cases (82.67％) were with complete response or response.There was no statistical difference between the 2 groups in curative effect (Z =-0.54,P =0.59).Forty-five cases in observation group were no response and accepted therapy,35 of them (77.78％) had response.There were equal efficiency in the initial therapy group and the subsequent therapy group (x2 =3.60,P =0.06).There was no difference between the age of onset,sex and season in 2 groups.Cases aged from 1 month to 1 year seemed to have a high incidence because of vaccination,and in the cases aged from 3 to 14 years the onset was related to infection.The children over 3 years old had higher risk factors in self-healing and the curative effect.There was no severe bleeding or adverse effect or dead cases in this study.Conclusions It is feasible to take platelet count ≤30 × 109/L as the threshold for initial therapy indications.Almost half of the cases could avoid overtreatment and pretherapy observation will not reduce the initial cure effect; no severe internal bleeding was observed in all the cases.

Objective To investigate the effect of intralesional lauromacrogol therapy on infantile hemangioma.Methods 30 cases all received intralesional injection of lauromacrogol.The changes of tumor size,texture and color were monitored and recorded.The adverse effects after medication were observed and managed accordingly.The adverse effects after medication were observed.The times of treatment were determined according to degree of reduction of tumor volume.To assess the efficacy,a 4 scales system was adopted.Results All patients had completed the treatment and followup.The overall response was scale Ⅰ in 2 cases (6.7 ％),scale Ⅱ efficacy in 4 patients (13.3 ％),scale Ⅲ efficacy in 5 cases (16.7 ％) and scale Ⅳ in 19 cases (63.3 ％).The smaller the tumor,the fewer the times of treatment,and the better the results.The effects of treatment were better if patient could be treated by intralesional lauromacrogol therapy in early stage.No severe adverse effects were observed during 6 months of follow-up.Conclusions Intralesional injection of lauromacrogol sclerotherapy is a safe and effective way to treat infantile hemangioma.

Objective To study the clinical,pathological characteristics and diagnosis of multiple system atrophy(MSA).Methods Among 4 cases of MSA,2 of them were from clinical data,the other 2were frum pathological data.Two cases verified by autopsy were investigated using Hematoxylin-eosi,Kltiver.Barrera and Gallvas-Braak silver staining and confirmed by immunohistochemistry using ubiquitin,α-synuclein staining.Results All 4 patients were male.aged 51-76.Case No.1 wag diagnosed as Parkinson's svndrome.Case No.2 was diagnosed as spinal ataxia cerebella,and the other two eases were diagnosed as MSA.The following changes were found by pathological studies.Macroscopic atrophies were presented in pens and cerebella.as well as putamen,globus pallidus and substantia nigra.Cerebral ventricles were dilated.Neuronal lOSS and gliosis could be seen at cerebral cortex.nigrostriatal.globus pallidus,pontine nuclei,subslantia innominata,inferior olives,doral motor nucleus of vagus,cerebellum antl intermediolateral column of the spinal cord.In the white matter of these regions cytoplasmic inclusions bodies were extensively present in oligodendrocytes.Conclusions Olivopontocerebellar atrophy mainly shows the,clinical symptoms of pens,cerebellum,and autonomic nerves damage;Shy-Drager syndrome presents mainly with the erecting hypotenstion symptom,while striatonigral degeneration mainly involves extrapyramidal system.As these three diseases share the common basic pathological changes,they are preferred to be classified as the subtype of MSA.
